Design of optimal impulse transfers from the Sun–Earth libration point to asteroid

Optimal transfer between elliptic orbits with three tangential impulses

“…The study of a multi-impulse transfer between two coplanar and Keplerian orbits is a classical problem of astrodynamics [1,2], which is usually analyzed within an optimal framework by looking for the transfer trajectory that minimizes the propellant consumption, the total flight time, or a suitable combination of these two quantities [3,4,5].…”
